The fabric has a ton of stretch, so my daughter can climb and scramble without it riding up. It kept her dry through a sweaty afternoon at the playground, and the hood actually stays put when she runs.
My son wore this on a full day of hiking and the FLASHDRY-XD fabric kept him dry even after he worked up a sweat climbing rocks. The stretch is real too, he never once complained it felt tight across the shoulders.
Bought this for my daughter's week at camp and it held up well through sweat and a few washes. Dries fast, which is the main reason I'd get another. Only gripe is the hood feels a bit thin when the sun is really beating down.
